 Hi, welcome to film my run, my name's Stephen Cousins. Here we are again at the worthy running track. We're gonna do another very exciting stride foot pod test. We're gonna use track run mode on the Garmin watch. I've got two Garmin watches on today, two Phoenix six watches, a 6s and a 6 pro sapphire. And I'm gonna use two separate stride foot pods. One is the stride wind and one is the old stride both connected by and plus because as I was so rightly told in the comments section of my last video, the stride team do not recommend, do not want you to connect via Bluetooth. They have very good results at all connecting the stride foot pod to Bluetooth through Garmin watches. So Garmin watches only do not connect through Bluetooth. It just doesn't work. Nobody knows why. Right, I've measured this track before. It is a certified UK athletics track. UK athletics licensed events do take place here so we know it's 400 meters but just because I have a new wheel, a new measuring wheel and I do like playing with measuring wheels, we're just gonna measure the track again. This is my new measuring wheel, look. It's a slightly bigger wheel so the error margin will be smaller. I think the error margin is about 0.5% on this particular wheel. We're gonna go around the track and make sure that it is 400 meters. We know it is but just for fun. Each 400 meter running track should be 400 meters from about 20 centimeters inside the edge of the first lane. So let's have a look at that. So here's the first lane. I reckon about 20 centimeters inside is around about here. It might be a bit more but that'll do for me. I'm not going to worry too much about it. Last time I measured it was about the 400 meter mark last time I measured was about here. So we're gonna go from here and see what it does. Okay, we're ready to roll. Just going to set the watches going. So we'll try and keep a fairly good path around the track. Hopefully we'll get a decent result. We've had a pretty good result at 200 meters. It was almost bang on 200 meters so I'm pretty pleased about that. So we'll carry on to the end and hopefully we'll hit 400 dead on. Well would you look at that? 400.3 meters. So I reckon most of the way we've been around 20 to 30 centimeters off the inside of the track. And I tried to walk a pretty even line. So I reckon we've got a good result there. I reckon we were about 20 to 30 centimeters off from the inside of the track. We weren't on the middle. So that's interesting that the last wheel I had I was measuring more in the middle of the track to get 400 meters whereas this wheel which is a little more robust, a little bigger wheel diameter. We've got a better result I think. And I've stayed pretty true as I walked around. So hopefully we're satisfied that this is a well measured track. So there we are. I'm pleased with that result. A larger diameter wheel seems to have given us less margin for error. And 20 to 30 centimeters from the inside of lane 1. We've got good 400 meter mark. Almost exactly 400 meters so pleased with that. So the next job is to calibrate the track run mode on the Garmin watches. I've done it once on this watch already but we'll do it again a couple of times around the track just so that the Garmin watches can map the track and know where the lanes are on the track. We're only gonna stay in lane 1 anyway but we may as well do it just to be sure. Hello editing Steven just butting in for one second. Just to make it absolutely clear I'm using track mode for two reasons and two reasons only. GPS is going to draw me a lovely map around the track. Track mode is great for learning what the track looks like and mapping it for you. So rather than having loads of squiggly lines or cut-off corners that GPS would normally give you, track mode gives you a nice smoother line round your track. We're not using GPS for distance or pace that is totally the stride foot pods that are measuring the distance. And the second reason for using track mode is it gives you meters to the meter. So you know like if you use a normal mode it will give you it will say 10.1 kilometers. Well this gives you 10,000 and 10 kilometers or 10,012 kilometers so we'll know to the meter what the measurement is. So that's another reason to use track mode. Also stay tuned at the end because although I finish on the track I'm gonna bring it back in here and we'll do a little bit of analysis of some numbers and some graphs on the computer so stay tuned for that at the end. Okay back to me running around the track. That's one lot done just go around one more time. There we are that's calibration done of the two watches. So I have my this is my wife's Garmin Phoenix 6S and that's got track mode on it and this is my Garmin Phoenix 6 Pro Sapphire. Both with track mode on both with stride foot pods attached. One is the stride wind attached to this watch and one is the old stride attached to this watch. Both foot pods are 100% zero calibration no calibration at all. Also calibration is disabled and they are both on always for distance and pace. So both set as always for distance and pace. So let's do 10,000 meters round the track. Let's see what distance we get at the end of that. So on my right wrist the Phoenix 6S is ticking over a lot earlier than the Phoenix 6 Pro Sapphire. I'm sticking to 10 kilometers in one hour according to the stride foot pod connected to my Phoenix 6 Pro and that's the wind stride and the old stride is connected to the Phoenix S and like I say that's ticking over earlier than the track markers and this one is ticking over much later than the track markers. So we're checking towards the end. Okay we're not far away from 10k now. This is the 25th lap so 10k is 25 laps of a track. Now the Phoenix 6S is going to finish early. The Phoenix 6 Pro is going to finish late. So let's just see how early and how late they finish. 58 minutes 9,970. I don't know if you can see this. I hope you can. 90. There's 10,000 meters there. 58 minutes 32 seconds and we are well we'll see in a minute how far short we are. This is the old stride foot pod connected to the Phoenix 6, Phoenix 6 and that has recorded 10,000 meters a bit earlier than you might want. On the track here we go up to the line and we are 90 meters short. So 90 meters. So if you've got an old stride foot pod and a Phoenix 6S you might think you've run 10,000 meters but you're 90 meters short. Unless you calibrate your stride of course. Right so let's see how far off the Phoenix 6 Pro is. 59, 30, 9, 59, 40. And here we go. Right there we go. Now how far back are we? Quite a way aren't we? There's the 200 meter line just there. The stride wind has been given every chance to measure short because it's the left foot so it's nearest the inner line but it's measured long and the old stride has been given every chance to measure long because it's nearer to the centre of the lane but in fact it's measured short. Okay I know what I'm going to do. I'm going to mark this spot here. I'm going to go and get the wheel and I'm going to measure how much further we ran than 10,000 meters. Final test of the day let's just measure how long the stride wind measured on my Phoenix 6 Pro. So here we are this is where I stopped running so we're going to walk back along the track around where my foot was and see how short we are. Okay there we are 170 meters long so the stride wind measured 170 meters longer than 10,000 meters. So that's it from what has become a pretty wet and windy morning on the wording track here. This is the second time I've measured the wording track with two different wheels and we have had slightly different results each time whether it was me walking around the track badly or whether it was a tolerance level and a margin of error level on each wheel I don't know but the second wheel I've used this bigger wheel I'm liable to trust that a bit more it has a better tolerance level according to the manual. So we either had 400 meters around the track from dead centre of the middle of lane one or we had 400 meters from around about 20 to 30 centimetres inside the inner edge of lane one. Take your pick doesn't matter whether that would add 170 meters or or take away 90 meters off your watch I don't I don't know depends how you run around the track doesn't it but you know we can safely say the tracks 400 meters and the stride wind measured 170 meters long uncalibrated 100 calibration and the stride old foot pod measured 90 meters short make of that what you will could be my bad walking around the track who knows could be my poor running 10,000 meters around the track but it doesn't matter in a race 10,000 meters on the track is 25 laps of the track so you'd stop here you'd stop at that line it doesn't matter what your stride foot pod says or what your watch says it's 25 times around the track and there it is so thanks very much for watching that is it any comments questions abuse obviously to leave that all down below and maybe I'll reply maybe I won't take care we'll see you for the next one bye bye okay welcome to the film I run shed quarters which can have a little look at some numbers just to try and explain this run a little more so we'll start off with speed here so I've got both the stride foot pods the phoenix 6 pro and the phoenix 6s watches showing speed here and you can see the blue one is the phoenix 6 pro which is the modern stride wind and that is clearly showing slower pace throughout the run the purple line is is the old stride foot pod clearly showing a faster pace throughout the run and you can see down here the average speed for the phoenix 6 pro is 10.1 kilometers an hour which is about right because I was running to that watch so making sure I did 10 kilometers in one hour according to that watch but the phoenix 6s has a speed of 10.27 kilometers per hour and you can see on the distance graph here as well the two runs diverge more and more the further along we go so another indication that both the strides are measuring different speeds different distances now what's interesting is we clearly know that the stride wind made me run an extra what did we say 170 meters and that might seem a lot when you when you look at it in terms of actual meters I ran 10,170 meters where I should have just run 10,000 meters and when you look at it in track mode it looks quite a lot but actually when you look at it on Strava you might just throw that 170 meters away because let me show you if we go to Strava here is my 10k track run and just about now an elapsed time of one hour and one second we've got a little difference there because I stopped to pick up the camera briefly on a couple of times so most of the time I was running around the track without the camera occasionally I just stopped quickly just to pick up the camera and carry on so that's what that difference is now this is 10 kilometers according to the stride wind but if we correct the distance so this is Strava's own analysis of the track analysis of the GPS track around the whirling track it will recalibrate the distance and tell me what it thinks I ran so let's press that button and say correct distance I wonder what it'll come up with let's see have to wait a couple of minutes for it to do its calculations oh look at that 10.1 X so this is saying I've run an extra 180 or so meters we haven't got the extra digit there have we so it could be 180 180 could be 189 but according to Strava we've run an extra 180 meters of distance but if you saw that in your race results if you saw 10.18 you would discard that 180 as a meaningless extra bit of data wouldn't you or you might do it anyway but it's so it's interesting to see it in track mode because it 180 meters or 170 meters really makes you think gosh yes I did run quite a bit of extra distance there so anyway there we are so that's my analysis I'll just change it back because I wanted to say 10k I don't care I don't care that I ran that extra distance but that just shows you doesn't it so there we are again like I said earlier take from it what you will it may mean that you want to calibrate your stride wind or your old stride foot pod it may not you may be quite happy with that stride may say that that extra distance or that under distance is within an acceptable margin of error and you know what it's not that bad is it really when you look at it okay take care that's it thank you very much for watching bye bye
